A cryptomining company recently deployed a new antivirus application to all of its mining systems. The
installation of the antivirus application was tested on many personal devices, and no issues were observed.
Once the antivirus application was rolled out to the servers, constant issues were reported. As a result, the
company decided to remove the mining software. The antivirus application was MOST likely classifying the
software as:


A. a rootkit.
B. a PUP.
C. a backdoor.
D. ransomware.
E. a RAT.
